Abstract: CONFORMANCE CORRECTION TO IMPROVE HYDROCARBON  RECOVERY      FROM A SUBTERRANEAN FORMATION                            ABSTRACT    A non-crosslinking salt of a monovalent cation is added to a gela-tion solution comprising an acrylamide polymer and a redox crosslinking system to render the viscosity and uniformity of the resulting gel less sensitive to the concentrations of the gel components.  The gel is used for  conformance  correction  treatments  of  subterranean  hydrocarbon-bearing  formations to reduce the permeability  of a  high  permeability zone adjacent a low permeability zone.

Abstract: Abstract Conventional electroplated steel sheets of Zn alloys of Zn-Ni base, Zn-Fe base, etc., having a poor phosphating performance, have been involved in the problems such that when used for automobile bodies, craterings may be generated on coating films at the time of electrodeposition coating to damage the coating appearance, or that only poor corrosion resistance and pin holing resistance can be achieved at the portions where no coating film is applied or only a thin coating film is applied for structural reasons of automobile bodies.  To solve such problems, this invention provides a multilayer zinc metal electroplated steel sheet comprising i) a lower layer electroplated coating provided on the surface of the steel sheet and comprising a Zn-Ni base alloy having Ni content of 10 to 16 wt.% or Zn-Fe base alloy having Fe content of 10 to 30 wt.%, containing 0.005 to 5 wt.% of at least one silica, alumina, titanium oxide, magnesia, chromium oxide and zirconium oxide, and ii) an upper layer electroplated coating provided on said lower layer electroplated coating and comprising an Fe-B base alloy having B (boron) content of 0.001 to 3 wt.% or an Fe-rich Fe-Zn base alloy having Fe content of 60 wt.% or more, so that the lower layer may contribute the improvement in the corrosion resistance and pin holing resistance and the upper layer may contribute the improvement in the phosphating performance.  The lower layer may preferably have a coating weight of 10 to 50 g/m2 per one side, and the upper layer may preferably have a coating weight of 0.5 to 10 g/m2 per one side.

Title: Fast curing phenolic resins
Inventor: DAISY NICK K
IPC: C09J161/06
Filed: 1987-08-26
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE      It has now been found that when there is a partial or complete replacement of the sodium hydroxide, that is used to make a sodium phenolate resole resin, by a molar equivalent of potassium hydroxide, a far faster curing resin is obtained. Such potassium-modified phenolic resins exhibit significant improvement in cure speed without loss of flowability. To the contrary, these resins act as though they were lower molecular weight condensation products. Reduced application rates are possible. The combination of faster cure and lower application rates has allowed such resins to be used as effective adhesives for plywood, for example, with veneer and interior plies having a higher moisture content than was previously possible.     Generally, resins according to the invention may contain from about 1% to about 15%, and preferably from about 1% to about 7% by weight, of potassium hydroxide, or more.

Abstract: ABSTRACT OF THE DISCLOSURE           A circuit for measuring the dynamic charac-teristics of encapsulating packages for high-speed integrated circuits includes at least two amplifiers integrated on a semiconductor substrate.  These amplifiers have the same input and output impedances as those of the high-speed circuit to be encapsulated within the package.  The amplifiers are located in widely spaced relation in order to ensure that there is no internal coupling.  Depending on the measurements to be performed, the two amplifiers are mounted in parallel or in antiparallel relation.  In order to measure the dynamic characteristics of a package, a measuring circuit is mounted within a package and a signal (Ve) is addressed-to an input connection of the package.  The transmission and coupling coefficients are deduced from measurement of the signal (VS) collected on an output connection.

Filed: 1988-04-21
Granted: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE:           A frame-like roller carrier which defines a sizing plane normal to the longitudinal axis of the can bodies is arranged in relation to a welding device in such a manner that the sizing plane coincides at least approximately with a welding plane defined by the welding device.  A plurality of sizing rollers are mounted on the roller carrier,  each for rotation about a roller axis lying in the sizing plane. The sizing rollers form a rigid ring of rollers through which the can bodies can be moved.  The roller carrier is divided into two half-frames,  each of which carries a plurality of sizing rollers.   The two half-frames are adjustably supported on a common bridge.  At least one of the half-frames is connected to the bridge by an adjusting drive for the adjustment of the sizing rollers carried by it.  Consequently, the sizing tool can be adjusted with little labour,  for example if the overlapping width of the can longitudinal edges to be welded to one another has to be altered.

A substantially closed circumferential wall is provided which connects the rear and front faces to enclose the fan blades approximately equal distant from the respective faces to prohibit the hand, figure or foot from reaching the blade path after passing partially through either face should a person unfortunately attempt to do so.

Abstract: The  peak  amplitude  values  of  two  different frequency pressure changes produced by the displacement device of a volume sensing arrangement, are obtained and one divided by the other to produce a value indicative of the volume of the unfilled portion of a storage vessel.   The contents  of  the vessel  are derived by subtracting  the unfilled  volume  from  the  vessel  capacity.     In  the embodiments a single pressure sensor is used, the signal is simultaneously filtered with a low pass filter and a band pass filter in order to obtain static and dynamic pressure data.  In some embodiments the single sensor is disposed in a chamber in which the displacement means produces two different frequency pressure variations.   The chamber is communicated with th storage vessel by a pipe the length and diameter of which are selected to prevent the pressure variations produced by one of the frequencies from being transmitted therethrough.  In other embodiments two pressure sensors are used and the special pipe dispensed with and the outputs of the two sensors fed to band pass filters.
